Abstract

PURPOSE:To obtain a fiberboard of high strength with a small quantity of adhesives by preparing a woody fiberboard by the dry process with POVAL (derivative) modified thermosetting resin adhesives. CONSTITUTION:After a previous boiling treatment, woody chips are disintegrated by a defibrating apparatus into fibers and at the same time POVAL-modified thermosetting resin adhesives such as urea, melamine, phoenol, etc. modified by POVAL or a POVAL derivative is thrown into this apparatus to obtain woody fibers coated with adhesives. Nixt, the adhesive-coated woody fibers are formed, heated and pressed in a hot press to obrain a woody fiber board. Said adhesives may be added to the woody fibers in another blender after the defibration of the chips into the woody fibers.
